There is a issue when adding rebar3_elixir_compile on global rebar3 config file

[minghu6]

When I add { rebar3_elixir_compile, ".*", {git, "https://github.com/barrel-db/rebar3_elixir_compile.git", {branch, "master"}}}, { rebar3_elixir_compile, {git, "https://github.com/barrel-db/rebar3_elixir_compile.git", {branch, "master"}}} or just rebar3_elixir_compile to the plugins of ~/.config/rebar3/rebar.config.

It always reports .config/rebar3/rebar.config exists but can not be read. Ignoring global config values.
However, If I change to other plugin like rebar3_hex, rebar_erl_vsn, all works.

Env

rebar 3.6.1 on Erlang/OTP 21 Erts 10.0
